  • Hello Guys,

    Thank you very much for your help. After the changed the target platform from "Any CPU" to "X64" and deployed it this issue is resolved.

    before that i registered it to GAC and also placed it D:\Program Files\Microsoft Dynamics CRM\CRMWeb\bin with no luck.

    Thanks

  • Hi,

    Is this a CRM4 ISV folder application - it seems there is a missing assembly - can you post what is in D:\Program Files\Microsoft Dynamics CRM\CRMWeb\isv\custom\web.config line 18

  • If your assembly is a Plugin or Workflow extension that relies on an alternate assembly, named 'Common.BO', then it's failing because 'Common.BO' is not deployed to the server in a fashion that ASP.Net is recognizing.  There are three methods for shipping supporting, 3rd-Party assemblies to a CRM deployment:

    1. Install the assembly into the Global Assembly Cache
    2. Deploy the assembly to the file system
    3. Package the assemblies together using ILMerge

    In all instances, your supporting assembly must be signed, which doesn't appear to be an issue since the reference appears to contain its Public Key Token.  Good luck!

  • Hello Scott & Dave,

    Thank you for your replies 

    * line 18 on web.config is  "<add assembly="Common.BO, Version=0.0.0.0, Culture=neutral, PublicKeyToken=bc8433c638c2f6d0" />"

    * installed the assembly on GAC (can't find it "C:\Windows\assembly" but is it added "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Common.BO\v4.0_0.0.0.0__bc8433c638c2f6d0")

    * assembly is also present in the bin folder of the application.

    Still the same error.

    I used fusionlogs and the log is as follows....

  • Put the assembly here:

    D:\Program Files\Microsoft Dynamics CRM\CRMWeb\bin

    At the end of your log, it's searching for the assembly, and not finding it in any location.  If you're sure it's in one of those locations, double-check the read permissions to the file.  It might have retained some of its properties when it was copied, and isn't allowed to be read by the IIS worker process.

  • It also looks like the assembly is not registered in the GAC properly. Assemblies build against .Net 3.5 or earlier will be in the GAC in %windir%\assembly, whereas those built against .Net 4.0 or higher will be in %windir%\Microsoft.Net

    I'm not sure if it's an issue, but a version number of 0.0.0.0 makes me just a little nervous. I'd try any other version number than that
